Joint Custody may be used once by a player to share ownership and privileges of any opponent’s bunny. A player that has no bunnies in The Bunny Circle may place Joint Custody under an opponent’s bunny and still be allowed to play Aggressive cards such as weapons and Choose A Carrot. Joint Custody is discarded when the bunny is moved to another player in The Bunny Circle, traded with another player, abducted or killed.
A player with Joint Custody of an opponent’s bunny is also the owner of the bunny. Therefore, any card that affects the player’s bunny (or bunnies) will affect the bunny in Joint Custody. A bunny in Joint Custody may be used to win the game.
